New Computer won't boot!

Alrighty, I just built myself a new computer and to say it's had a few problems would be an understatement. At first, there was no display at all on the monitor. The fans booted up and such but no image. I tried two different video cards on two different monitors and that changed nothing. I ended up switching the RAM position in the motherboard which solved that problem. The computer, at one point, didn't even turn on when I pressed power! That was fixed by putting one of the jumpers on the motherboard back on (It was probably knocked off when switching vid cards or something), but only after I took out the PSU and actually checked it with a multimeter (it was fine). I was finally able to install windows 7 and even run a few programs and play some games. I only installed drivers for the video card, which i assume wasn't enough but everything was running fine.

Now comes the current problem.

After I left my computer in sleep mode for a few hours and came back, it was in the windows repair screen. It was finished, so I let it boot to windows, but as soon as it got to the windows loading screen, it restarted! It kept going in this restarting loop. I opened it up, played around with things and after taking off the CPU heatsink and putting it back on, it booted to desktop again. Yay, problem solved... Or so I thought. It did this everytime I turned the computer off, so everytime I played around with the heatsink and it eventually would boot up. Now, no matter how much I move things around, it won't boot up. It even started this weird "pulsing" where the lights go on for half a second then turn off and it does this a few times before the fans and stuff actually go on.

In short, my computer always restarts at windows loading screen, I thought it was the cpu overheating, but now I'm not so sure.

OS: Windows 7 64-bit
CPU: Intel i7 920
Motherboard: Asus, can't tell you more atm, I'm at work and don't have all info
Video Card: 295 GTX
HDD: Velociraptor 300gb ~250gb free
DVD drive: Some dell thing, worked fine in other computers
PSU: 850W Coolmaster, again at work don't have more info
RAM: 3x 2gb DDR3 Zenith @ ~1280MHz

Do you guys have any ideas as to why this is happening? I didn't need to pay this much for a paper weight :mad:

If you need more info, just ask. Though I won't be able to pull up a dxdiag, I'll do my best to provide the info you need
 
i would re-install windows, but after you get it on put all the mobo and vid card drivers on instead of just the vid card ones.

make sure you have the square 4 pin 12v power pluged into the mother board. there is a 24 pin and a 4 pin that you have to have pluged in
 
Yes, I've got both the 24 and the 4pin (thought it was 6) on the mobo. Would reinstalling windows really help? Could that explain the odd "pulsing" I was seeing, where it would just sorta on off really quickly?
